Chuchu

Serving as Anthy’s loyal companion and familiar, this tiny marmoset provides much-needed comedic relief throughout the series. Although Anthy affectionately refers to him as a friend, his presence often signals approaching misfortune during pivotal episodes. While the anime adaptation depicts him with mouse-like features, the original manga by Chiho Saito portrays a much fluffier, more detailed primate, highlighting the subtle visual differences between the two versions of this iconic sidekick.
